La Hacienda is a Mexican restaurant downtown that offers an excellent buffet of Mexican food for a very reasonable price. One item not on the menu is "cabrito" goat, which you have to ask for and it is excellent, succulent meat, beautifully roasted. Each day the restaurant roasts one goat in the morning and sells it until it runs out. Get there early! Their coffee is great and compares well to Starbuck's.
Lorina's Cantina, outside of town on US 90 toward the Lake, has steak night on Wednesdays from 6:00 to 8:00. Call ahead to reserve a steak. The steaks are about 3/4 to 1 lb in size, thick cut, wonderful, beautifully seasoned, succulent, and come with a baked potato and salad only lettuce and dressings bar for only $13 per person. This is a real meal for meat-and-potato-kind-of-guys.
T&B Todd and Bullet's Bar and Grill next to the Day's Inn on US 90 has good food and a good bar. Anthony Bourdain of the Travel Channel once came here for their Corona Chicken, which is succulent pieces of chicken about the size of the neck of a Corona bottle filled with cheese and wrapped in bacon.
Chinto's on Sixth street has excellent Mexican food and generous portions in a comfortable atmosphere for very resonable prices. Hours about 6:00 a.m. to 2:30 p.m. per many traditional Mexican restaurants.
Standard fast food Wendy's, Whataburger, etc. and chains Chili's, Luby's, etc. are available.
There is one Thai restaurant, Jitra's, in town with mediocre Thai food.
